Donepezil treatment in Alzheimer’s disease patients with and without cerebrovascular lesions: a preliminary report
Aim: Donepezil has not been evaluated in Korean patients with Alzheimer’s disease (AD) for up to 1 year. The objectives of this study were to evaluate the differential efficacy of donepezil in Korean AD patients with and without concomitant cerebrovascular lesions (CVL).; Methods: This study was a 48-week open-label trial of donepezil in patients with […]

Docosahexaenoic acid supplementation and cognitive decline in Alzheimer disease: a randomized trial
Context: Docosahexaenoic acid (DHA) is the most abundant long-chain polyunsaturated fatty acid in the brain. Epidemiological studies suggest that consumption of DHA is associated with a reduced incidence of Alzheimer disease. Animal studies demonstrate that oral intake of DHA reduces Alzheimer-like brain pathology.; Objective: To determine if supplementation with DHA slows cognitive and functional decline […]

Postmenopausal hormone therapy and subclinical cerebrovascular disease: the WHIMS-MRI Study
Objective: The Women’s Health Initiative Memory Study (WHIMS) hormone therapy (HT) trials reported that conjugated equine estrogen (CEE) with or without medroxyprogesterone acetate (MPA) increases risk for all-cause dementia and global cognitive decline. WHIMS MRI measured subclinical cerebrovascular disease as a possible mechanism to explain cognitive decline reported in WHIMS.; Methods: We contacted 2,345 women […]

Ibuprofen treatment modifies cortical sources of EEG rhythms in mild Alzheimer’s disease
Objective: Non-steroidal anti-inflammatory drugs such as ibuprofen have a protective role on risk of Alzheimer’s disease (AD). Here we evaluated the hypothesis that long-term ibuprofen treatment affects cortical sources of resting electroencephalographic (EEG) rhythms in mild AD patients.; Methods: Twenty-three AD patients (13 treated AD IBUPROFEN; 10 untreated AD PLACEBO) were enrolled. Resting EEG data […]

A phase I trial of deep brain stimulation of memory circuits in Alzheimer’s disease
Objective: Alzheimer disease (AD) is characterized by functional impairment in the neural elements and circuits underlying cognitive and memory functions. We hypothesized that fornix/hypothalamus deep brain stimulation (DBS) could modulate neurophysiological activity in these pathological circuits and possibly produce clinical benefits.; Methods: We conducted a phase I trial in 6 patients with mild AD receiving […]

Randomized controlled trial of atorvastatin in mild to moderate Alzheimer disease: LEADe
Background: There is some evidence that statins may have a protective and symptomatic benefit in Alzheimer disease (AD). The LEADe study is a randomized controlled trial (RCT) evaluating the efficacy and safety of atorvastatin in patients with mild to moderate AD.; Methods: This was an international, multicenter, double-blind, randomized, parallel-group study. Subjects had mild to […]

Goal-oriented cognitive rehabilitation for people with early-stage Alzheimer disease: a single-blind randomized controlled trial of clinical efficacy
Objectives: To provide evidence regarding the clinical efficacy of cognitive rehabilitation (CR) in early-stage Alzheimer disease (AD).; Design: Single-blind randomized controlled trial comparing CR with relaxation therapy and no treatment.; Setting: Outpatient, community-based setting.; Participants: Sixty-nine individuals (41 women, 28 men; mean age 77.78 years, standard deviation 6.32, range = 56-89) with a diagnosis of […]

Longitudinal changes in white matter disease and cognition in the first year of the Alzheimer disease neuroimaging initiative
Objective: To evaluate relationships between magnetic resonance imaging (MRI)-based measures of white matter hyperintensities (WMHs), measured at baseline and longitudinally, and 1-year cognitive decline using a large convenience sample in a clinical trial design with a relatively mild profile of cardiovascular risk factors.; Design: Convenience sample in a clinical trial design.; Subjects: A total of […]

A single ascending dose study of bapineuzumab in patients with Alzheimer disease
The safety, tolerability, and pharmacokinetics (PKs) of bapineuzumab (AAB-001), a humanized monoclonal antibody to amyloid beta, were evaluated in patients with mild-to-moderate Alzheimer disease in a phase 1, randomized, third-party unblinded, placebo-controlled, single ascending dose trial. Thirty patients received bapineuzumab infusion of 0.5, 1.5, or 5 mg/kg or placebo (6 active, 2 placebo for 0.5 […]

3D comparison of low, intermediate, and advanced hippocampal atrophy in MCI
We applied the hippocampal radial atrophy mapping technique to the baseline and follow-up magnetic resonance image data of 169 amnestic mild cognitive impairment (MCI) participants in the imaging arm of the Alzheimer’s Disease Cooperative Study MCI Donepezil/Vitamin E trial. Sixty percent of the subjects with none to mild hippocampal atrophy rated with the visual medial […]
